RE46C162/163

CMOS Ionization Smoke Detector ASIC with Interconnect,

Timer Mode and Alarm Memory

Features

Description

• Pin Selectable Horn Patterns

• Alarm Memory

The RE46C162/163 devices are low-power, CMOS

ionization type, smoke detector ICs. With few external

components, these circuits will provide all the required

features for an ionization type smoke detector.

• Sensitivity Control Timer:

- 8 minute Timer for RE46C162

- 1 minute Timer for RE46C163

• >1500V ESD Protection (HBM) on All Pins

• Guard Outputs for Ion Detector Input

• ±0.75 pA Detect Input Current

• Internal Reverse Battery Protection

• Low Quiescent Current Consumption (<6.5 µA)

• I/O Filter and Charge Dump

An internal oscillator strobes power to the smoke

detection circuitry for 10.5 ms every 1.67 seconds to

keep standby current to a minimum. A check for a low

battery condition is performed every 40 seconds when

in standby. The temporal horn pattern supports the

NFPA 72 emergency evacuation signal.

An interconnect pin allows multiple detectors to be

connected so when one unit alarms, all units will sound.

A charge dump feature will quickly discharge the inter-

connect line when exiting a local alarm. The intercon-

nect input is also digitally filtered.

• Internal Low Battery Detection

• Power-up Low Battery Test

• Interconnect up to 66 Detectors

• RoHS Compliant, Lead Free Packaging

An internal timer allows for a single button, push-to-test

to be used for a reduced sensitivity mode.

An alarm memory feature allows the user to determine

if the unit has previously entered a local alarm

condition.

Utilizing

low-power

CMOS

technology,

the

RE46C162/163 devices are designed for use in smoke

detectors that comply with Underwriters Laboratory

Specification UL217 and UL268.
